Cenote – Ancient Gate with Water Wheels and Spigots
East Side (part 1)

After you get the first waterwheel moving, as shown in the previous section, dive into the pool and swim down to the moving wheel on the left (east) side.

Wait for the opening in the wheel to align with the opening in the wall behind it and swim through.

Then make your way under the central walkway into the east side of the pool.

There are a few items on the bottom, including a resource canister behind a wooden barrier in the northwest corner of the pool.

Take what you can carry and climb out on the north ledge. If you like, you can use a rope arrow to pull down the wooden barrier to the left of the stairs. This isn't necessary but will allow you to get back to the center walkway. The last the effigy (5/5) for the Respected Challenge is at the top of the stairs. Use a rope arrow to pull it down and complete the challenge. Loot the resource container in the alcove at the top of the stairs.

Climb onto the higher ledge on the east side of the cavern.

There's another winch here, but it's not safe to use it yet. Take cover on the left side of the stone column, as 2 archers appear on the ledges to the south.

Use your bow or rifle to take them out.

Then move to the top of the stairs on the left.

Two Yaaxil warriors approach from below. They come one at a time, so you can shoot with bow, rifle, or even pistol as they approach; or wait until each one gets close and blast him with the shotgun or use the Puma's Feint/Dodge Kill.

Loot the corpses and gather arrows and shotgun ammo between the stairs and the winch...

...and more shotgun and rifle ammo near one of the columns.
